scan-near.

To all whom it may concern:

Be it known that I, FRANKLIN L. Games, a citizen of the United States ofAmerica, residing at Grand Rapids, in the county of Kent and State ofMichigan, have invented certain new and useful Im rovements invRoad-Floats; and I do here y declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same. I

My inyention relates to improvements in road floats, and its object isto provide a simple effective device having various new and usefulfeatures hereinafter more fully described and particularly pointed outin the claims.

My device consists essentially of a series of beams horizontallydisposed, arranged in parallel relation and spaced apart, cr nnc'tingbars pivotally attached thereto, whereby the beams are adjusted, and abraceadjustably connected thereto whereby the bars are held inadjustment at various distances from each other and overlapping eachother more or less. a blade attached to the first beam of the series,the same being recessed at intervals at its lower edge and the metalbetween the recesses twisted to form diagonal cutting blades, andstraight edged scraping'blades attached to the remaining beams, as willmore fully appear by reference to the accompanying drawings in which:

Figure 1 is a perspective of a device embodying my invention andadjusted foruse; Fig. 2 a plan view of the same; Fig. 3 an enlar eddetail of a portion of the cutting blade an beam in elevation; Fig. 4the same showing an inverted plan; and, Fig. 5, a transverse section ofthe same on the line 5-5 of Fig. 3.

Like numbers refer to like parts in all of the figures.

1, 2, and 3 represent a series of beams horizontally disposed and spacedapart in parallel relation, said beams being preferably angle iron barseach with its horizontal-memher above and a downwardl extended verticalmember at the rear. hese beams are connected by channel bars pivotallyattached thereto by bolts 11, whereby they are spaced apart at variousdistances as referred, and will overlap and extend partially beyond eachother in series according to adjustment. To adjust and hold these beamsand bars, a brace bar 5 preferably of angle Patented April 20, 1909.

1 iron is pivotally connected to the front beam 1 near one end thereof,and adjustably connected to the rear beam 3 near the other end by a bolt6 adjustable in a series of openings 7, in the horizontal member ofthebeam 3.

To the vertical member of the forward beam 1 is bolted a 'strip of metalnear its upper edge arranged substantially vertical an extending belowthe beam, that portion below the beam being recessed or slottedvertically at regular intervals and twisted to form diagonally disposedcutting blades which cut and turn the soil. To the vertical member ofeach remaining beam is attached a scraping blade 8 consisting of arectangular strip of steel which smooths and levels the soildisintegrated by the cutting blades on the beam 1.

12 are shackles on the beam 1 by means of which any suitable means ofmoving the device forward may be attached. The tendency of the beams isto turn somewhatdiagonal to the direction of movement due to thelaterally pro'ecting position of the successive beams whereby thetendency of the device is to move the material longitudinall of thecutters and scra ers and thus more effectually pulverize an move thesame, the

degree of projection and distance apart of.

the beams being determinedsby the adjustment of the brace bar 5 relativeto the openin 7;

' What I claim is:

1. A road float comprising a series of horizontally disposed beamsspaced apart, bars connecting the beams and pivotally attached thereto,a brace bar adjustably connecting the beams, a disintegratin memberattached to the forward beam, -an a straight edged scraper attached toeach remaining beam.

2. A road float com rising, three angle iron beams, two channe barspivotally connected thereto and adjustably spacin the same apart, abrace bar pivoted to one eam a plate attached to the forward beam andhaving its lower edge vertically recessedand twisted out of' alinementforming mchned attached to the remaining beams.

an -le iron beams spaced apart in parallel relation and each having ahorizontally d sposed upper member and a vertically disposed rearmember, two transverse channel cutters, and straight edged scrapingblades- 3. In a road float, the combination of three and ad ustablyconnected to another beam,

bars pivotally attached to the beams, a brace 1 rectangular plateattached to the vertical 1?. bar plvoted to the forward beam andadjustmember-0f each of the other beams. ably attached to the rear beam,a disinte- In testimony whereof I affix my signature grating memberattached to the forward. in'presence of two witnesses.
